UNITED STATES HERMAN D. SCHNEIDER, OF BRUNNER, ONTARIO, CANADA.

ELEVATING LOADER. `l

Application filed May 2,

To el] whom t may concern.'

Be it known that l, HERMAN D. SoHNEiDER, of Brunner, in the county of Perth, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improvements in lillevating` Loaders, of which the following is a speciiication.

This invention relates to devices for picking up hay, grain or similar outcrops from the lield and loading it into a wagon or other receptacle and particularly to apparatus specially adapted for elevating and loading sheaves from the shocks, and my object is to devise apparatus of this kind which is complete in itself, except for its power plant, and means of propulsion. and which is adapted to be'coupled up with a suitable tractor, such as may be purchased in the open market. so that it may be propelled by said tractor and its elevation and conveying mechanism driven therefrom,

l attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in whichn Fig. l is a side elevation of the loader;

Fig. 2 a front elevation of the same;

Fig. 3 a plan view of the same with parts removed; and

Fig. l a detail in perspective of the spring suspension for the front axle. f n' f ln the drawings like numerals of reference indicate corresponding parts in the different figures.

The frame of the loader comprises side members lA suitably connected by'transverse members and formed preferably of structural steel angles. These side members are arched intermediate their ends to give the center of the frame greater clearance from the ground than towards the' ends to avoid any possibility of the frame striking knolls or bumps which may be straddledbv the supporting wheels of the apparatus. Preferably the arch is formed by using short lower sills 2 at the under side of the side members of the frame which are connected by the inclined members 7 with the upper sill of the side frame. A longitudinal. brace l connects these inclined members as shown to give proper strength at the otherwise weak point where the inclined. members meet the upper sill of the side frame. Other arrangements might, of course, be used to provide the necessary arch. This varch is particularly necessary ill VGW Of the Ldjustable side member of the loader frame.

Serial No. 466,196.

spring suspensions for rthe steering wheels and rear wheelsy of the frame which l will now describe.v

The rear wheels 5 are journalled on stub axles 6. Each stub axle is carried by a snpporting bracket comprising a plate 7 and braces 8 to which the stub axle is connected. The plate- 7 is vertically movable in guides 9 formed 'on the side member of the frame. vvpspring suspension is provided between each stub axle supporting` bracket and. the

frame. `In the preferred construction a semi-elliptic spring l0 is secured intermediate its ends in any suitable manner to the stub axle. One end of each spring is pivotally connected at ll to the side member of a frame, which the other is preferably supported by a pivoted shackle l2 to compensate for the lengthening and shortening` of the spring under varying loads.

rlhe forward end of the frame is provided with steering wheels 1 3 which are journalled in a manner known in the art on spindles 14- journalled on vertical axes l5 at the ends of the front axle 16. A spring suspension is provided for this front axle, which preferably comprises the semi-elliptic springs 17 secured to the axle in a known manner. Ono end of each spring is pivotally connected to the frame, while the other end is connected with a pivoted shackle 1 8 forming a compensating connection to take care of my lvaryinglengths et the spring due to variations in load. The shackle is pivotally connected with a vertical barl9. which 1s slidable in suitable guides formed on the sidel member of the frame. The bent brace 20 is also provided supporting the outer side of the shackle. The other end of the spring is connected with a pivot bolt 2l adapted to nass through any one pair of holes formed the vertical members 22 connected to the The position of the frame relative to the spring is thus readily adjustable by altering the positionA of kthe bolt pivot 2l and by vertically adjusting the slidable bar 19.

Any suitable means may be provided for vertically adjusting this bar. I show the bar as having a rack 23 formed at its upper end, with which. rack engages a pinion 245 machine.

which leads to a position for convenient operation as hereinafter described. The spindle 25, it will be noted extends across the machine, where the pinion 24 and the rack 23 are duplicated so that both springs 1T may be simultaneously adjusted.

Suitably connected to the forward end of the frame is the frame 29 of the elevator. This elevator is of ordinary type provided with elevator slats 30 connected to the chain 31 carried by suitable sprocket wheels 32 journalled at the top and bottom of thel frame.l A suitable picker drum 10() is journalled at the lower end of the elevator. which may be of any type, such. for example as that shown in my prior Patent No.

Suitably supported from the main frame and the elevator frame is the transverse con veyor 34, which may be of'any ordinary type such. for example@ as that shown in the prior Patent 1,255,470. Feb. 5. 1918, hereinbefore referred to.

The shaft 35 carrying the upper sprockets 32 forms the drive shaft for the conveyor and elevator system and this shaft is driven as hereinafter described. This shaft is connected with a shaft 36, preferably7 by means of a universal joint 37, and this shaft 36 is connected by means of a universal joint 38 with a shaft 3,9 journalled on the frame of the conveyor 34. This shaft 39, by means of bevel gearing 40, aetuates the spindle /ll carrying the driving sprockets 4-2 of the transverse conveyor.

An important feature of my invention is the provision for propelling the same and for driving the elevator and conveyor. l employ as the power plant an ordinary tac* tor. The tractor is received within the frame at the rear of the machine and is coupled so as to float relative to the loader frame. At the rear end of the frame is located a gate comprising a cross member formed of suitable angles suitably connected and secured to the side members l of the loader frame by means of removable bolts 414i. Diagonal braces l5 are providedv extending from the cross members of the gate to the side members l to which they are secured by removable bolts 4G. By removing the bolts at one end of the gate and by also removing the bolts between the braces 45 and the side members 1. the gate may be swung wide open to permit of the entrance of the tractor. The fore wheels of the tractor are removed and the forward end of the tractor is supported loosely on the frame of the For this purpose I provide the transverse yoke member 4:7 which has its ends rounded form `journals and sup ported in open bearing members 48 secured to the side members 1 of the loader frame. This yoke is provided centrally with an up standing lug` li9 adapted to be received between lugs formed en a bracket secured beneath the forward end of the tractor. A king` pin 51 passes through the lugs. lWhile the tractor is thus supported by the yoke member, it is free to rock laterally relative thereto, which rocking movement of the tractor and the loader frame relative to one another is provided for by the journalling of the ends of the yoke member. The bearings being open above the yoke, the member is easily dropped into place. To tie the sidemembers 1 of the loader frame together beneath the tractor, I provide the transverse brace 52 suitably connected to the lower sills of the side members 1. The rear end of the tractor is provided with the usual draw bar connection 53, which7 when the tractor is in place within the frame, is bolted to the draw bar 54- which curves upwardly and rearwardly and is adapted to slide vertically on two guide members 55 secured to the gate. Coil springs 56 are preferably placed about these guides and engage the underside of the top member of the gate and the upper Side of the drawy bar, so that a certain amount of the weight of the rear end of the loader frame is taken by the draw bar. Diagonal bra-ces 57 are bolted to the draw bar 54 and to the rear end of the tractor as shown to assist in taking the strain due to the downward pressure of the coil springs 56. From the construction described it will be seen that the tractor as a whole is floatingly supported relative to the loader frame and at the same time is effectively coupled to the frame so that its power may be used to propel the latter7 which is, however, supported substantially only by its own ground wheels.

The tractor is preferably so positioned that the axis of its master wheels 5S is substantially in the same vertical plane as the axis of the stub axles 6 or at any rate not very far therefrom, as this facilitates the steering of the device by the steering wheels 13.

The arrangement described provided as effectively for the propulsion of the apparatus as if the power plant Ywere built into the latter, while the tractor, not being permanently a part of the machine, is always available for other service when not required in connection with the loader.

It is important that the device as a whole, including` the tractor5 be controlled from a position where the operator has a full view of both the positions of the work to be effected and also of the discharge end of the transverse conveyor. I therefore provide an operator-"s platform 59 at the left hand side of the upper end ofthe elevator and in front of the transverse conveyor, this platform being suitably supported from the frame. To this platform all the controls of the apparatus are led. For instance. the spindle 2S for adjusting` the vertical slide bar 19 is led to this platform and is provided necting the steering arms 7l of the spindlesV 14 carrying the steering wheels. This mechanism is, of course, old in the art and may be arranged in many ways. So also various engine controls may be led to the operators platform 59. As these may be arranged in many different ways, I show only one in detail7 viz. the controlling means for the gear shift lever 72 of t-he tractor, which will usually be of the ordinary type in which the gears are shifted laterally by fore and aft n'iovements of the lever. An upward eX- tension 73 is bolted to the ordinary gear shifting lever and to this lever is pivotally connected an operating rod, the upper end 74 of which is located in a position convient to the operators platform. This rod is provided with a lateral crank 75, Lwhich is adapted to both rock and slide laterally in brackets 76 secured to the loader frame.

T'o the end of the portion 7 5 is integrally or otherwise connected a depending portion 7 7 which in turn connects with a rearwardly extending portion 78, which is pivotally connected with the upper end of the extension 73 and the `gear shift lever.` This portion 7 8 is slidable in a guide 79 secured to the frame. The guide 79 also serves as a fulcrum on which the portion 78 may rock in a substantially horizontal plane. It is evident that by pushing the upper end 74 of the operating lever laterally that the gearv shift lever will. be pushed laterally, and that by rocking the upper end 74 either backwards or forwards the gear shiftvlever will be correspondingly rocked.

To drive the elevator and conveyor T provide the following mechanism. A sprocket wheel 80 is secured to each master wheel of the tractor, which sprocket wheels yare connected by means of sprocket chains 82 with sprocket wheels 83 which are looseon the shaft 84 ournalled on the loader frame. Each sprocket chain is provided with a 'grooved tightener pulley 97 journalled on sprocket wheels may be given a driving connection with the shaft. This shaft carries a belt pulley 86 which drives a belt 87, which in turn drives a pulley 88 on the shaft 35 which carries the upper sprocket wheels 32 of the elevator, thus driving the elevator and from it the lateral conveyor `as hereinbefore described. The clutches 85 are controlled from the operators platform in 'the following manner. A T-shaped pivoted clutch shift lever 90 suitably pivoted on the frame of the machine directly engages one of the clutches. With an upward extending arm on this clutch shift lever a rod 91 is pivotally connected, which is forked at its other end and engages a collar 92 carried by the usual grooved collar of the farclutch. To the arm 93 of the clutch shift lever is pivotally connected the operating rod 94, which leads up to a suitable means for holding it in either the clutching or declutching position, as, for example, the end of the rod may be formed with a handle 95 which may be held in a fork 96 when the clutches are to be held out of engagement.
